Photomechanical effect is the change in the shape of a material when it is exposed to light. This effect was first documented by Alexander Graham Bell in 1880. More recently, Kenji Uchino demonstrated that a photostrictive material could be used for legs in the construction of a miniature optically-powered "walker". … See more • Smart materials See more • The Nonlinear Optics Web Site See more WebIn this Review, we focus on light as an energy source and describe the recent progress in the area of soft materials that can convert light energy into mechanical energy directly (photomechanical effect), especially the photomechanical effects of LCEs with a view to applications for light-driven LCE actuators. hilton grand vacations las vegas hotels

WebMay 15, 2024 · Photomechanical effects in materials can directly convert light stimulus into mechanical work. The magnitude of the photogenerated work is directly associated with the material stiffness (modulus). Here, we report the synthesis of an azobenzene-functionalized polyamide (azoPA) and demonstrate its room-temperature photomechanical response. WebWavelength dependence is initiated by the mechanistic contribution of network pull-effects, directly controlled by isomer population, whereas photomechanical contributions from constant molecular oscillation between cis and trans states is independent of isomer population and is directly connected to the system's temperature.
